Rest Server Returns HTTP 405 Error

[Shannon Sims]

Hello all and thanks for reading my post!

I’m trying to get my client communicating with the Rest server. I found this link: http://www.theserverside.com/tip/RESTful-Web-services-made-easy.
When I try to invoke a simple service using the example code, I get “HTTP Status 405 - specified HTTP method is not allowed for the requested
resource ()”. The web.xml in the example shows a servlet mapping to a Jersey ServletContainer. I’m not using Jersey; is there a different
ServletContainer I should use instead? If I do, will this conflict with the HttpServletDispatcher?

Web.xml

Figured out my issue:

You need to set the “resteasy.servlet.mapping.prefix” if your servlet-mapping for the resteasy servlet has a url-pattern other than “/*“.

The resteasy servlet url-pattern is “/rest/*“, so you have to set the “resteasy.servlet.mapping.prefix” to “/rest” as well, otherwise, you will hit resource not found error message.
